I went the other way. I had cats for 28 years and then inherited a dog when I had 2 remaining cats. When the dog was the last to go over the rainbow bridge, I was widowed with an empty house and CHOSE to my get own dog rather than another cat. He's a Border Collie.
Believe me, dogs may need walking up to 4 times a day but they do what they are told.
Lie down
Bed
Stay
Come
Shush
I now realise that I was a hostage to my cats (I had 4 at one time) and I knew how to be totally subservient. After a long day at work, I never took my coat off until I had answered the wowls for food, and change the litter tray. I was used to cats round my ankles whilst I cooked liver and bacon - knowing I would get the smallest serving.
I would relax on the sofa, but jump up 50 times a night to open the back door to let the cats out, open the patio doors to let them in, open the back door again to let another out..... ad infinitum. When they were all in at the same time, I sat on the floor whilst the cats had the 3-piece suite. I was lucky to get 12 inches of bed at night (and on a good night I even got a pillow!)
Of course I know that I was very honoured to have been allowed to share the cats' 4-bed detached house with them. One cat even checked out my NEW towels by scratching and nesting in them in the airing cupboard to test their quality before I was allowed to use them. I think she lubbed me extra-speshully.
Some tips
Your lap must be available at all times - even if that is when you are sitting on the loo.
Wear fluffy slippers so that when you are walking you are providing hunting/playful opportunities.
If you step on your princess by accident, say you are sorry immediately!
When you are put in your place with back-turning and ignoring, have plenty of treats (like Dreamies) to coak her to forgive you.
If she looks at you like you are a piece of shit - you are! You are bothering her ............ so stop it!
